I have 3 Clematis planted in containers. They were all received just a few weeks ago and planted up in Urns. They all have bamboo tee-pee's. One of them has grown so vigorously that it is now taller than the tee-pee. What should I do ? Do I prune it back ? or let it continue to grow ?
Thanks for any help anyone can offer me.

How about larger teepees? Is there enough room to add a 6' teepee?

Here's Liberation, from a few years ago. You can see how fast it grew - more than amazing. It got to 5'5" in 34 days.


Some clematises will zoom while others won't. There's no way to tell what will happen.

Wow, well, I would have to look for much longer bamboo stakes - the ones I'm using now are only 25" in length. My Clematis 'Rosemoor' is growing very very fast in leaps and bounds. You're right, I may need longer bamboo stakes! Thanks for the recommendation.

There is clear netting in the garden departments of big box stores so maybe hanging the netting from a tree would be simpler than trying for the larger bamboo. This one is 6.5' x 30', for $20.00 so it appears to be a good buy. http://www.gardeners.com/buy/t...

Well, 4 of my Clematis are planted in Large Stone Urns. So I am using the bamboo stakes to support the vines. I don't think netting would work for clematis planted in urns. But thank for
the idea.

I do wish you luck. When plants grow too well it's difficult to offer sympathy!

figuring out the bloom times of the 3 varieties is where you need to start. randomly "cutting them back" is a bad way to look at it if you're concerned about flowering. spring bloomers will flower on growth that was put on last year. summer bloomers flower on new growth from this year. cutting them back is a crap shoot unless you know when they flower. its good for size control however.

Rosemoor is a summer bloomer, so cutting it back now in order to determine a course of action will probably not harm the flowering aspect. it may delay it though. but as fast as it appears to be growing, I wouldn't worry about it too much!

@AlanJ - maybe you could put a tall (lifeless) branch in the pot and secure the branch to the current support. I wouldn't use anything that might root!
